Application filed December 28, 1899. Serial No. 741,815 (No model.)

To all whom it may concern:

Be it known that I, LEONIDAS G. WOOLLE Y, a citizen ofthe United States,residing at Kenton, in the county of Hardin and State of Ohio, haveinvented certain new and useful Improvements in Telephone and Fire-AlarmSignals; and I do declare the following to be a full, clear, and exactdescription of the invention,such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of referencemarkedthereon, which form a part of this specification.

My invention relates to an improvement in telephone and. fire-alarmsignals; and it consists in the arrangement and combination of parts,which will be'more fully described hereinafter.

The object of my invention is to have the telephone automatically turnin a fire-alarm to the central at the same time the occupants of thebuilding are notified and to so construct the parts that if a person istoo nervous to operate the telephone he has only to break the pane ofglass in a door of the telephoneboX, when the alarm is sounded andtransmitted to central.

In the accompanying drawings,Figure 1 is a front elevation of myinvention complete, showing the door of the telephone-box open and alsoshowing the fire-alarm placed upon the same base as the telephone. Fig.2 is a side elevation of the telephone-box alone containing theoperating mechanism. Fig. 3 is a vertical section through the box, takento one side of its center, so as to show my operating mechanism. Fig. 4is a detail view of a portion of the operating mechanism. Fig. 5 is aperspective of the vertically-moving frame M and the casting T. Figs. 6and 7 are detail views of the generator-shaft and the parts connectedthereto.

A represents the base, upon which the swinging transmitter-arm B, thebox C, containing the operating mechanism, and the firealarm D aremounted. The swinging transmitter 13 is mounted upon the vertical rod Eand is adapted to be adjusted vertically upon this rod, so as to beadapted to the height of the person using it. In the box 0 is placed theusual magneto-electric machine F for signaling,and its shaft G extendson through the magnetomachine and through the opposite side of the box,where it is connected to the spring K, placed in the drum H. This shaftdoes not extend continuously across, but is divided just inside of thebox, and upon the two abutting ends of the shaft G are placed two disks1, one of which is provided with a ratchet a and the other with a pawlZ). WVhen an alarm is turned in to central, the shaft G is revolved byits handle in the usual manner, but it does not operate the spring; butwhen the spring causes the drum H to revolve the pawl 19 engages withthe ratchet a and causes the shaft to revolve, so as to transmit asignal to the central. The drum in revolving,'actuated by the spring K,placed inside of it, turns the shaft G in the same direction that itwould be turned by hand when a person turns in a signal, and in causingthe shaft to revolve the signal is antomatically transmitted to thecentral. This drum H and spring K are never operated except in turningin a fire-alarm signal.

In the front lower portion of the box containing the operating mechanismis the usual lever L, which cuts in the transmitter and cuts out thegenerator, and hence need not be more fully described. Also in the frontportion of the box is the electromagnet M, placed in the localthermostatic circuit and which when energized attracts the armature N,which carries a catch 0 for holding the door P closed. Also placeduponthe door P is the ringing apparatus Q, of the ordinary construction. Thelever L instead of projecting through the side of the box, so as to hangthe transmitter R upon in the usual manner, has connected to it a rod S,which extends down through the bottom of the box and connects with thelever T, upon which the receiver'is hung in the usual manner. The leverT is placed below the box. instead of inside of it as a matter ofconvenience, because the drum H takes up the room upon the side of thebox in such a manner as to make it desirable to drop the lever down, ashere shown. Pivoted in the front portion of the box at one side is thetriangular-shaped being strained when the frame U is brought intooperation. This frame swings through a very small arc of a circle andhas secured to it the rod V, which bears against the inside of the glassdoor for the purpose of pushing the door open, so that its end under thetension of the spring W can swing outwardly. The outer free end Z of theframe U projects through a slot X in the side of the box, as shown inFig. 1, and catches over the projection A, secured to the side of thedrum, and

thereby prevents the drum from revolving until the door is either openedor the glass in it is broken. The instant the door is opened, which maybe done by the short-circuiting of the thermostat system or by breakingthe glass, this end Z is swung outward by the spring W, as shown in Fig.3, sufliciently far to release the projection A upon the side of thedrum H, and then the spring K causes the drum to revolve, so as to turnin a firealarm to the central. In order to limit the distance the drumshall turn, the stationary stop B is secured to the side of the box, andwhen the drum has made nearly a full revo lution the projection Astrikes against the stop B. Before another fire-alarm can be turned init is necessary to windup the drum and make the end Z of the frame Ucatch over the top of the projection A on the drum, as shown in Fig. 2.Then by closing the door the pressure of the glass against the rod Vwillhold the frameUpressedinwardlyagainst the tension of the spring Wand the end Z over the top of the projection A.

In order to make sure that a fire-alarm is turned in whenever the dooris opened or the glass in it is broken, I pivot in the side of the box ashort shaft 0, which has upon its outer end a lever D, which extendsupwardly either against or in close proximity to the side of the drum H,and upon this upper end is placed a blade-like extension E. Upon theinner end of the shaft 0 is an arm G, which bears against the extensionH on the frame U and upon the upper end of the lever D, and extending atright angles thereto is an arm I,

which is secured to its outer end, and extending through the side of thebox is a pin J, which pin moves in the slot K. As soon as the door isopened or the glass broken the spring W starts the frame U to turnupon'its pivot, so that its free end swings outward, and thus leaves thedrum H free to revolve. When the drum has nearly completed itsrevolution, the projection A strikes the bladelike extension E andforces the lever D backward the fulllength of the slot K. The arm G willpush against the entension I-l, forcing the free end of the frame Uoutward. By this construction in case the spring WV does not move theframe U sufficiently to release the alarm mechanism the fire-alarm willbe turned in by direct positive action, the alarm being operated by theframe striking the lever Gr.

Pivoted at L in the top of the box at one side, so that it bearsdirectly against the side of the box, is a rod or frame M and which isprovided with the slots N and O and which has secured to it ablock-likeextension P, and to which extension is connected a spring S for thepurpose of moving the frame M upward when it is left free to move.Through the slot N passes a guiding-screw, and into the slot 0 projectsthe end of the lever L, so that when the spring S raises the frame M thelever cuts in through the spring R the local circuit for the transmitterin the usual manner and through the spring S the signaling apparatus.Althoughaspringis shown as hearing against the lower end of the frame Min Fig. 3, this is not necessary. Also secured to the inner side of thebox along the side of the frame M is a casting T, which has a projectionU extending outwardly toward the door and to which the outer end of thespring W is fastened and also has attached to it a spring V, which bearsagainst the armature N and normally holds the armature back until it isenergized by the magnet to allow the door to open.

In case a fire-alarm is turned in when no one is around and the receiveris suspended from the lever T in the usual manner, it will be impossiblefor the alarm to be transmitted as long as this lever and the lever Lare depressed, for the local transmitter and the bat tery are cut out.In order to instantly raise both of the levers L and T and to out inboth the battery and the transmitter, the end of the lever L is made toextend into the slot 0 7 i in the frame M, and then this frame is pushedlaterally at its lower end by means of the pin J. When the fire-alarm isturned in, the spring S instantly raises the frame M and by drawingupward upon the outer end of the lever L raises the lever T through theconnection S, with the weight of the receiver R upon it. The pin J bearsagainst the blocklike extension P, which serves to keep the frame Mdepressed by catching under the stop A on the casting T. When the fire.-alarm is turned in, the outward movement of the lever D causes the pin Jto strike against the block 1? and swing the frame laterally, so thatthe block P is moved from under the step A, and then the spring S isfree to raise the frame M and through this frame the levers L and T. IBy this construction it will, be seen that it is not necessary for aperson to be present when the thermostat turns, in the alarm, or when aperson is too nervous to use the transmitter and signaling apparatus inthe usual manner the alarm can nevertheless be sent in. To the two posts0 are connected the telephone-circuits in the usual manner, and to theposts D is connected a thermostatic circuit, which also operates in theusual manner. The wires of the thermostatic circuit extend through thebuilding in the usual manner and are connected to thermostats of anysuitable construction in each room or wherever desired, and in case of afire they complete the circuit, and thus turn in the fire-alarm throughthe mechanism above described. One of the wires of the thermostaticcircuit connects with the magnet which operates the catch upon the door.

When the thermostat turns in an alarm, it opens the door of the boX, andthe gong is operated mechanically by the outward movement of the frameU, which operates the lever G, pivoted in the bottom of the box, andwhich trips the spring-actuated mechanism forsounding the gong. There isnothing new in this part of the construction, and hence these circuitsare not shown in detail. The magneto calls up the central station, andthe operator there hears the gong ring. This thermostat is not necessaryto the operation of the fire-alarm, for the mere breaking of the glassin the door would be sufficient to turn in an alarm automatically, sothat while this thermostatic circuit is a great additional protectionand adds to the value of the invention accordingly it can be dispensedwith where watchmen are always on duty. The breaking of the glass in thedoor allows the frame U to move outwardly, and this open ates the leverG so as to sound the gong.
